Channel Selection for Rendezvous with High Link Stability in Cognitive Radio Network
Cognitive Radio Networks Channel Selection Problem Rendezvous Problem Link Stability
2016/1/22
Channel selection is a fundamental problem in Cognitive Radio Networks (CRNs). One basic channel assignment problem is ren-dezvous, which investigates how secondary users can establish a connec-tion b...
We fabricated and characterized the hydrogenate amorphous-silicon thin-film transistor (a-Si:H TFT) pixelelectrode circuit with the current-scaling function that can be used for active-matrix organic ...
Stochastic stability of the discrete-time constrained extended Kalman filter
Extended Kalman filter constrained Kalman filter stochastic stability
2010/10/12
In this paper, stability of the projection-based constrained discrete-time extended Kalman filter (EKF) as applied to nonlinear systems in a stochastic framework has been studied. It has been shown th...
Stability Analysis of a Closed-Loop Control for a Pulse Width Modulated DC Motor Drive
pulse width modulation (PWM) DC drive stability analysis
2009/7/28
In this paper, the effect of the variation of amplitude and the chopping period of a PWM signal on the stability of a closed-loop control for a DC motor drive is investigated. First, the entire system...
Amplitude and Frequency Control: Stability of Limit Cycles in Phase-Shift and Twin-T Oscillators
Frequency Control Limit Cycles Phase-Shift Twin-T Oscillators
2010/12/6
We show a technique for external direct current (DC) control of the amplitudes of limit cycles both in the Phase-shift and Twin-T oscillators. We have found that amplitudes of the oscillator output vo...
Nanocrystalline TiO2 Electrodes Exhibiting High Storage Capacity and Stability in Rechargeable Lithium Batteries
Nanocrystalline TiO2 Electrodes Lithium Batteries
2010/12/14
Nanocrystalline TiO2 films were explored for the first time as electrode material for a rechargeable lithium intercalation cell, i.e., Li/LiCF3SO3 + PC/TiO2. Two kinds of nanocrystalline films, TiO2 F...
A New Stability Test for Passivated NiCr Thin Film Resistors
passivated NiCr thin film resistors Arrhenius type
2010/12/16
A suitable short-time test for analysis of long term stability is presented for the case of passivated NiCr thin film resistors revealing an aging characteristic which is not of Arrhenius type. Based ...
Stability and Performance Characterization of Thick Film Microresistors
Thick Film Microresistors parasitic resistance high frequency applications
2010/12/21
In recent years, interest in the performance of small dimension resistors has increased primarily due to the need to reduce parasitic resistance in high frequency applications. This paper presents res...
Stability Observations and Surface Analysis of Air Fired Nickel Thick Film Conductors
Air Fired Nickel Thick Film Conductors conductive paste ESL 2554 96% Al2O3 substrates
2010/12/23
The results from an investigation of the properties of air fired Nickel thick film produced with conductive paste ESL 2554 on 96% Al2O3 substrates are described. The analysis of the possible causes of...
The Effect of High Speed Laser Trimming on Accuracy and Stability of Thick Film Resistors
High Speed Laser Trimming Thick Film Resistors
2010/12/28
Many recommendations have been made on the proper operating conditions for the laser trimming process. In general these recommendations have centered on accuracy, precision or throughput. In some inst...
